I'm interested in how people integrate diverse types of knowledge,
from document collections to the work of people with different kinds
of expertise. I study interdisciplinary scientific
collaborations with the NASA
Astrobiology Institute, and social Q&A communities--for
details, see my Research page. I'm
also helping develop Learnamic, a
site where homeschooling parents and children can discover and share
learning resources. If you're interested in any of these
projects or programs, feel free to contact me.
